I just found a repository of Scala based templating languages here: http://scalate.fusesource.org/documentation/index.html
One of the them is called ssp, for Scala Server Pages! But it's not really that interesting. Jade is interesting. But I think the most intersting one (on quick perusal) is scuery http://scalate.fusesource.org/documentation/scuery.html It shows how one can have simple html pages as templates and inject behavior into them from scala without the html people needing to do anything else than produce xhtml with their trusted tools.
